It's crucial to find food, water and shelter if you want to survive

Here are some of the best tips that would help you survive if the world went into melt-down…

Water

Research reveals that the average human can only survive for up to three days without water.

The body can become extremely dehydrated, especially if you were to be battling stress during a crisis.

For this reason, it’s important to find a water source that is safe to drink from.

Consuming fluids that haven’t been properly decontaminated can cause a number of medical problems, including vomiting, diarrhoea, nausea, fever, chills, and abdominal pain.

After finding a water source, it's important to purify the fluid before drinking

Most people won’t have water purification tablets to hand, so it can be a tricky task to get hold of safe drinking water.

Boiling it is the best and easiest option and requires the water to be heated 149F.

Starting a fire is important for warmth and to boil up water

Another method which doesn’t require much equipment is Solar Disinfection.

Survivors must place water into a clean plastic bottle into direct sunlight for at least 12 hours, which will help to kill bacteria lurking inside the fluid.

Food

Foraging could be dangerous unless you test the food items first

It’s a no brainer that humans need food to survive, but finding nourishment by foraging could be a deadly decision.

As many wild plants are toxic, it’s important to carry out some tests before eating them.

Survivalist advises:

Smell the plant to check whether or not it has an unpleasant aroma

Place a portion of plant onto your skin for a bare minimum of 15 minutes. Observe the location for signs of reaction

See how your body has reacted the plant after eight hours

If there has been no side-effects, place the plant onto one of your lips to see if you experience a burning or itching sensation

After three minutes with no reaction, you can attempt to consume a small quantity of the plant

Wait eight hours to see if you notice any side-effects before eating any more of the plant

As well as living off vegetation, survivors can attempt to hunt animals for food.

Setting traps and snares for the creatures is a clever way to capture them without using weapons.

The best way to set a snare, according to Survivalist

- The loop of the snare should remain unrestricted and open, allowing it to tighten on an animal when activated
- The loop of the snare should be kept up off the ground, preferably at the height of the target animal’s head
- Refrain from traversing, or interfering, with game trails when setting snares. The scent of a human will discourage the animal from using the path
- Site snares on well-worn game trails that display an abundance of activity, near an animal’s den, and/or near a feeding ground
- Camouflage the snare with foliage from the surrounding area. This camouflage should be situated in such a manner as to assist directing an animal to the actual snare

Shelter

It’s advisable to find shelter during a crisis in order to keep off the elements.

When setting up camp, it’s important to find an area that is away from too much open space but is still exposed to sunlight.

Resting a stick shelter on some healthy trees can provide your camp some stability

This will prevent all your hard work being blown away by the wind while also allowing some warmth into the structure.

Make sure not to set up your shelter near an unstable or pest-ridden tree, as they could prove hazardous.

A simple way to build a proper camp is to balance branches across two healthy trees, as this will provide some much-needed structure.

Barter

Survival can be a lot easier if you're not just relying on yourself.

In a crisis, traditional forms of money lose value - so maybe don't rely on the coins that you find around the house.

Using practical items to swap with strangers can help secure your survival, including coffee, blankets and water.

It's also advisable to keep hold of items that won't ever go down in value.

Bartering with precious metals such as gold and silver is also recommended by Survivalist.

While currency can fail during times of war, these rare materials will always keep their value.
